Physical Development
6
During the first 8 weeks, the tiny embryo develops fingers, toes, eyes, ears, a nose, a mouth, a heart, and a circulatory system. At 8 weeks, the 1 ½ -inch long embryo becomes a fetus and the organs of the various body systems develop to the point at which they can sustain the life of the baby after he/she is born. **Within 9 months of pregnancy, the embryo develops from a nearly microscopic cell to a baby about 20 inches in length.
